Absolutely. Look into using parameters In a calculated field, and use it as on the dashboards. This essentially will allow you to swap the dimension members (or swap measures) in your charts. You may even be able to use just one dashboard with one or more parameters. Very powerful feature of Tableau.

Thanks Matthew. I have used parameters in the past but this does not solve it.

The executives do not have any kind of training and hence I am sending them a workbook which has all the 5 dashboards pertaining to 5 territories. Each dashboard will show data related to an individual territory.
